Let me check, why do you have to include AH by the application in the
first place? Is that related to the question you made the other day
(attached below)?

Hi Team,
I want to use IPsec engine with AH Security Association and SPD on multicast
destination adress. When I comment the setsockopt MULTICAST_IF option, all
work fine and destination packets to the multicast adress have AH added
before IP Header. But when I use the setsockopt MULTICAST_IF, no packets are
sended from the interface (packet seems to be destroyed silently by kernel).
Is there an issue about using MUTLICAST_IF option and IPsec ?
Any help will be greatly appreciated.
Regards,
spe.
